PRINTING-MACHINE.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed June 5, 1909. Serial No. 500,313.

following is a specification.

This invention relates to printing-machines for printing multiple copiesof letters, circulars and the like.

The invention is directed to the provision of a printing-machine foroffice use, which is small and inexpensive to manufacture, which may berun by an unskilled operator,

and which is capable of printing in imitation of typewritten work.

More particularly, the invention is directed to the provision of aprinting-machine having a pressure-roller arranged for movement in onedirection in 'coaction with the type to effect the printing, and theninthe other direction on the opposite side of the type and the supporttherefor to return it to initial position in readiness for a repetitionof the operation.

In accordance with my present invention, a platen is provided which ismovable toward and away from the printing faces of the type, but theprinting is not effected primarily by this movement of the platen;instead, the type are arranged for movement in the direction of theirlengths and the pressure-roller is causedto engage the rear ends of thetype and move the type so as to cause their printing faces to pressagainst the impression-sheet with the desired pressure.

My invention 'is directed particularly to the provision ofsheet--feeding devices and sheet-delivery devices in combination with aprinting-machine of the type in which the pressure-roller is caused tomove in one direction on one side of the type-form to effect theprinting and in the other direction on the other side of the type-formto return to initial position. In accordance with this feature of theinvention, sheetfeeding devices are arranged upon one side of themachine and feed the sheets successively from this side into theprinting position. I have found that by so arranging the sheet-feedingdevices greater convenience in operation is secured and the parts .ofthe machine may be more compactly arranged. The sheet-delivery devicesare also arranged at one side of the machine, so that the sheets afterthey have been imprinted upon are fed from the printing position into asuitable tray at the side of the machine. Preferably both thesheet-feeding devices and sheet-delivery devices are arranged upon thesame side of the machine, one directly below the other, this arrangementof the parts contributing to the compactness of the structure.

I have illustrated the preferred embodiment of my invention in theaccompanying drawings, in which- Figure l is a plan view of the machinebroken away and sectioned in part; Fig. 2 is a central vertical sectionof the same on line 2-2 of Fig. 3; Fig. 3 is a section of the machine ona plane transverse to that of the section of Fig. 2; Fig. at is ahorizontal sectional elevation on line 4:-4: of Fig. 3; and Fig. 5 is anend view of the parts illustrated in Fig. 4.

Referring to these drawings, the machine consists of a base A on whichare mounted side-frames A, A Extending between these side-frames are twoshafts C, G, journaled in bearings formed in the side-frames and eachcarrying two sprocket-wheels 0, one adjacent to each of the side-frames.A chain 0 lies adjacent to each side-frame and runs upon two of thesprockets 0 upon the shafts C, C. Overlying each chain c is a cam 0having a straight edge inter-v mediate its ends, this cam beingadjustable vertically by means of nuts 0 on threaded studs secured tothe cams, these nuts lying between offsets formed on the side-frames.Extending between the chains 0 and mounted for rotation in bearingsformed in the chains, are one or more pressure-rollers D, D. The linksof the chains 0 in'which are formed the bearings for the ends of theshafts of the rollers D, D, are enlarged somewhat, so that they coactwith the faces coaction with the type, at a speed equal to that at whichthe roller rotates while in coaction with the type. Any suitable meansmay be provided for rotating the shafts C, C, and thus moving therollers D, D, as, for instance, the crank 6Z2 shown in Fig. 1.

Extending between the side-frames of the machine are two bars E adaptedto support the chase in which the type are mounted. This chase E is arectangular frame having flanges, as shown in Fig. 2, for engaging thebars E. Extending across the chase E are a plurality of bars 0 formingchannels in which the type 6 are inserted with their printing facesdownward. These type are provided with shoulders intermediate their,ends, adapted to engage the bars 6 to hold the type in position.Overlying the rear upper ends of the type 6 is a pad 6 of yieldingmaterial, such as rubber, the upper surface of this pad lying above theupper surfaces of the chase E and bars 6. As the machine is adaptedparticularly for use in printing in imitation of typewritten work, anink-ribbon F is shown as extending over the printing faces of the type,this ribbon having its ends wound upon spools f at opposite ends of themachine and rods or rollers f being provided extending between theside-frames of the machine to properly locate the ink-ribbon withreference to the printing faces of the type. If desired, means may beprovided for feeding the ink-ribbon F in the direction of its lengthintermittently during the operation of the machine, as, for instance, byhaving a projection on one of the chains 0 actuate one of the spools f.

Directly below the type is a platen G .arranged for vertical movementtoward and away from the type. Extending clownwardly from the under sideof the platen G are pairs of bifurcated standards 9 which straddleshafts 9 extending between the side-frames of the machine and mountedfor rotation in bearings formed therein. The

shafts 9 have cams g secured thereto, one adjacent to each standard 9,and each of these cams is adapted to coact with a roller 9 mounted forrotation upon the standard 9. At one side of the machine, the shafts gextend beyond the side-frame A and carry gears g which are connectedtogether by an idler-gear g mounted for rotation upon a stubshaftprojecting from the sideframe A. On the shaft O, outside the sideframeA, is a gear meshing with one of the gears 9 so that when the machine isoperated by means of the handle (Z the shafts 9 will be rotated.

The sheets to be imprinted upon are fed into the machine from afeedingtable H at the side of the machine, through an elongated slotprovided in the side-frame A and between the platen G and the ribbon Funderlying the printing faces of the type. The mechanism for feeding thesheets into printing position may be constructed in various ways, but;prefer to employ for this purpose an apparatus constructed in accordancewith Patent No. 929,292, dated July 27, 1909, this consisting of a pairof sheet-feeding rollers and one or more reciprocating grippers, thelatter being adapted to grip a sheet and forward it until its edge iscaught between the two sheet-feeding rollers, whereupon the latterforward the sheet to its proper position.

In the accompanying drawings, I have shown auxiliary frames 72,projecting outwardly from the side-frame A and having sheet-feedingrollers h and If mounted for rotation in bearings formed therein andgeared together by means of intermeshing gears 7L secured upon theshafts thereof. These rollers are of sectional form, as shown in Fig. 1,so as to provide spaces between the adjacent sections thereof into whichthe reciprocating grippers may enter. The upper gripper I consists of asheet-metal strip shaped as shown in Fig. 3 and having its ends bentdownwardly and pivotally con nected to the ends of a bar 2' adapted toreciprocate beneath a sheet-metal extension 2" of the feed-table 8. Tothe bar '5 are secured the lower grippers J, these consisting of stripsof sheet-metal bent as shown in Fig. 3, so as to provide in each aportion coacting with one of the fingers of the upper gripper I andhaving its upper surface lying in the plane of the upper surface of thefeedboard. To the under side of each gripper J is pivoted a stop Khaving an upwardlyturned forward end projecting through a slot in thegripper J. At its rear end each stop K is bent to provide an inclinedportion is adapted to engage a strip is when the stop is moved forwardlywith the grippers, so as to turn the stop upon its pivot and thus causeits upwardly turned end to be drawn down below the upper surface of thegripper J.

Upon each of the downwardly turned ends of the upper gripper I, is atrunnion, which is received in a slot formed in the upper end of a leverL mounted upon a shaft pivoted in the auxiliary frame it. Springs Z areconnected to the lower ends of these levers L and normally hold them inthe positions in which they are shown in Fig. 3 with the grippersretracted. The shaft C is extended through its bearing in the side-frameA and carries a gear Z meshing with a gear Z upon a short shaft mountedin a bearing formed upon the side-frame A this shaft carrying a cam Zupon which rides a roller Z carried by a crank Z secured to the shaft Zupon which the levers -L are mounted. The plate 2" is extended beyondthe sheet-feeding rollers 7L, k

through the slot provided in the side-frame A so as to guide the sheetproperly into the printing position. In this position, the movement ofthe sheet is arrested by a plurality of stops 0 at the opposite side ofthe platen G.

After the sheet has been imprinted upon, it is delivered by moving it inthe direction opposite to that in which it was moved by thesheet-feeding devices. This is effected, first, by moving the stops 0,which push the sheet edgewise before them until its opposite edge passesbetween two delivery rolls P. These rolls are geared together by meansof intermeshing gears 39 and the shaft of one of the rollers carries aspiral gear p meshing with a similar gear upon the shaft C. Each of thestops 0 is pivotally connected to the lower end of a link 0, the upperend of which is pivotally connected to the support E for the chase E. Aspring 0 is connected to the link 0 and tends to move the link in adirection to carry the stop O to the right in Fig. 3. A spring 0connects the stop 0 and the link 0 and acts upon the stop so as to holdits end down upon the surface of the platen G. Each stop 0 is providedwith a downwardly extending portion 0 on the end of which is a toothcoacting with a cam formed upon the side of a disk 0 secured to one ofthe shafts 9 The operation of the machine will now be described. Byturning the handle d the shafts C, C, are rotated and the rollers D, D,are caused to move in one direction over the form of type and thenreturn to initial position below the type-form. The shafts g aresimultaneously rotated, and just as one of the pressure-rollersapproaches the position for coaction with the type, the cams 9 upon theshafts g raise the platen G to such a position that the sheet of paperupon the platen is in contact with the ink-ribbon F directly overlyingthe printing faces of the type, this upward movement of the platen Gpreferably being such that the type e are raised slightly, these typebeing loose in the channels between the bars 6. Then as the operation ofthe machine continues, the pressure-roller engages the type e throughthe yielding pad 6 and presses these type down, so as to cause them toimprint upon the sheet through the ink-ribbon F. After thepressure-roller passes beyond the type, the cams 9 permit the platen Gto move downwardly again to its initial position. .The feeding of thesheets to the printing position takes place while the platen G is inthis downward position. The initial position of the sheet-feedingdevices is that shown in Fig. 8, with the grippers separated, and thestops K having their forward ends raised. A sheet of paper is fed byhand between the grippers until its movement is arrested by its edgeengaging the upwardly turned ends of the stops K. At the proper timewith relation to the movement of the platen G and pressurerollers D, D,the cam Z turns the shaft Z so as to rock the levers L. These levers actfirst upon the upper gripper I through the trunnions connecting thisgripper to the levers, by turning the gripper upon its pivotalconnection to the bar 2' which carries the lower grippers J. Thisturning movement causes the upper gripper I to grip the sheet between itand the lower grippers J, whereupon further turning movement of theupper gripper is precluded, and the continued movement of levers Lcauses the upper and lower grippers to move forwardly until their endsenter the spaces between the sections of the sheet-feeding rollers h,77/ The sections of these rollers then grip the edge of the sheet andthe rotation of the rollers causes the sheet to be fed forwardly intoprinting position until its movement is arrested by the stops 0. As soonas the sheet-feeding rollers grip the sheet, the latter is released bythe grippers, due to the fact that at this time the cam Z permits thelevers L to be returned to initial position by springs Z. The firstportion of this return movement causes the upper gripper I to be turnedon its pivotal connection to the bar 2', so as to separate the twogrippers. The sheet is then imprinted upon by raising the platen G asheretofore described, and when the platen is so raised the stoplevers 0are turned on their pivots in a clockwise direction against thetensionof springs 0 After the sheet has been imprinted upon and theplaten Gr lowered, the cams 0 move the stops 0 to the left in Fig. '3and these stops push the printed sheet ahead of them until the oppositeedge of the sheet is gripped between the deliveryrolls P, which deliverthe sheet through the opening provided in the side-frame A as shown atthe left in Fig. 8, into a suitable tray mounted to receive it.
